Lower values of optimum cooking time and loss of solids are
quality characteristics that were used to select the most desirable
fresh spaghetti. The choice of intermediate values of mass increase
and lower chroma b* values were set by comparing the values of
the experimental design to those obtained for wheat flour fresh
spaghetti (Table 4). The diagram of the desirability test indicated that the most suitable formulation consisted of 66.5 g 100 g1 DPP,
9.5 g 100 g1 EPP and 24 g 100 g1 AF. Thus, FS6 was considered the
most desirable sample because of its ranking on the desirability
test, that is, a proportion of 65:10:25 of the components listed
above, respectively. Using a scanning electron microscopy, FS6
showed a better surface, which confirmed the results of the desirability
test (Fig. 3F).
